Koihime 2: vol.1

Musashi came back to his village again. He had lost his memory about the four princesses who had been his friends, and also forgot that he had sexual intercourse with them. Though he lost his memory, the village and his grand mother's house made him think familiar. He was welcomed at his grandmother's home, and met a girl named Tamamo. She said she was his friend, but he couldn't recall her at all. At night, he was lured by a strange smell, and did things with Tamamo. However it was the beginning of the plot of a person who wanted to revenge himself on the village leader using Musashi.
